01 — Composition / Colour / Light
A low knot opens outward. Sparse left, dense right; open blue slows the eye.
Deep blue × pale cyan: tonal contrast makes the outline clear; neighbouring hues keep it quiet.
The pale branches blocked light. The facing-page shadow belongs to the album photograph.

02 — Process / Artist / Feeling
Sensitised paper → specimen → exposure → wash. Branches leave a direct impression.
Anna Atkins, an early British photographer, began publishing her cyanotype algae album in 1843.
The outline holds a moment of contact. A precisely named life keeps an unmeasurable silence.
The seaweed left the page. Light kept its outline.
03 — Practice / Sources
Paper 65% · blue 30% · cyan 5%. A design suggestion, not a measured palette.
Keep its weight slightly low. Leave the top third open; place a small label below.
Branches should remain distinct. If they merge, enlarge the image and cut the text.
